Clinical studies serve evidence-based medicine and enable the development and application of new, innovative medical products and drugs. At the moment, there are several clinical studies with chitosan-containing products or devices, for example, in relation to wound healing, tumor detection or Covid-19. In this article, we would like to give you an overview of the ongoing studies.

Medical masks proved effective in protecting against the virus during the Covid-19 pandemic. However, conventional masks are poorly biodegradable. For this reason, the presented paper produced environmentally friendly chitosan/silver/plant fiber membranes for masks, which also exhibited antibacterial and thermal properties.

Deeper skin injuries require appropriate wound dressings to promote healing. In the presented study, CMC-containing hyaluronic acid-dopamine hydrogels were synthesized, characterized and investigated in vivo for their wound healing properties.

Breast cancer will affect one in eight women during their lifetime. Especially metastatic breast cancer has a low survival rate. In this article, we present a review of current research on the use of chitosan in breast cancer therapy and diagnostics.

Fungi of the Candida genus can be responsible for serious skin infections, especially as biofilms. To find an alternative treatment method for fungal biofilms, chitosan-gold nanoparticles were coupled with the quorum sensing molecule Tyrosol in the study presented here.

Around one third of all type-2 diabetes sufferers develop diabetic foot ulcers in the course of their disease. Due to biofilm formation and multi-resistant bacteria, inflammation occurs in 50% of those affected. This article presents a study investigating the treatment of these with chitosan-containing metallic nanoparticles coupled to toluidine blue as a photosensitizer.
